the day preceding the first Floating Rate Interest Payment Date occurring after such date and, thereafter, the period commencing on each Floating Rate Interest Payment Date and ending on the day
preceding the next Floating Rate Interest Payment Date. 
 “LIBOR” shall mean the rate as published by Bloomberg (or
another commercially available source providing quotations of such rate as selected by the Company from time to time) at approximately 11:00 a.m., London time, two Business Days prior to the commencement of the relevant applicable quarterly Interest
Period, as the rate for dollar deposits in the London interbank market with a three-month maturity. If such rate is not available at such time for any reason, then the rate for that Interest Period will be determined by such alternate method as

designated as ranking junior to the Notes by express provision in the instrument creating or evidencing such obligation. The securing of any obligations of the Company, which obligations otherwise have a ranking junior to the Notes, shall be deemed
to prevent such obligations from constituting obligations ranking junior to the Notes. For the avoidance of doubt, any junior subordinated debt securities issued or assumed by the Company shall be deemed securities ranking junior to the Notes other
than any such securities issued after the date hereof that by their terms expressly rank on a parity with the Notes. 
 “Ranking on
a Parity with the Notes”, when used with respect to any obligation of the Company, shall mean any obligation of the Company which (a) ranks equally with and not prior to the Notes in right of payment upon the occurrence of any
Proceeding or (b) is specifically designated as ranking on a parity with the Notes by express provision in the instrument creating or evidencing such obligation. The securing of any obligations of the Company, which obligations otherwise have a
ranking on a parity with the Notes, shall not be deemed to prevent such obligations from constituting obligations ranking on a parity with the Notes. 

“Senior Debt” shall mean all of the Company’s: 

(a) indebtedness for borrowed or purchased money, whether or not evidenced by bonds, debentures, notes, or other written instruments; 

  
 - 4 -

(c) indebtedness or other obligations with respect to commodity contracts, interest rate and currency swap agreements, cap, floor, and collar
agreements, currency spot and forward contracts, and other similar agreements or arrangements designed to protect against fluctuations in currency exchange or interest rates; 

(d) obligations to its general creditors (as defined for purposes of the capital adequacy regulations of the FRB applicable to the Company, as
the same may be amended or modified from time to time); and 
 (e) guarantees, endorsements (other than by endorsement of negotiable
instruments for collection in the ordinary course of business), and other similar contingent obligations in respect of obligations of others of a type described in the immediately preceding clauses (a), (b), (c) and (d), whether or not such
obligation is classified as a liability on a balance sheet prepared in accordance with accounting principles generally accepted in the United States, in each case whether outstanding on the date of this First Supplemental Indenture or arising
thereafter, and other than obligations Ranking on a Parity with the Notes or Ranking Junior to the Notes. 
 Notwithstanding the foregoing,
and for the avoidance of doubt, if the FRB (or other successor regulatory agency or authority) promulgates any rule or issues any interpretation that defines general creditor(s), the main purpose of which is to establish criteria for determining
whether the subordinated debt of a bank holding company is to be included in its capital, then the term ‘‘general creditors’’ as used herein shall have the meaning as described in that rule or interpretation. 

“Tax Event” shall mean the receipt by the Company of an opinion of independent tax counsel to the effect that as a result of
any amendment to, or change (including any announced prospective change) in, the laws or any regulations of the United States or any political subdivision or taxing authority, or as a result of any official administrative pronouncement or judicial
decision interpreting or applying such laws or regulations, which amendment or change is effective or which pronouncement or decision is announced on or after the date of the issuance of the Notes, there is more than an insubstantial risk that the
interest payable on the Notes is not, or within 90 days of receipt of such opinion, will not be, deductible by the Company, in whole or in part, for U.S. federal income tax purposes. 

“Tier 2 Capital Event” shall mean the receipt by the Company of an opinion of independent bank regulatory counsel to the
effect that, as a result of: 
 (a) any amendment to, or change (including any announced prospective change) in, the laws or any regulations
thereunder of the United States or any rules, guidelines or policies of an applicable regulatory authority for the Company; or 
 (b) any
official administrative pronouncement or judicial decision interpreting or applying such laws or regulations, which amendment or change is effective, or which pronouncement or decision is announced, on or after the date of this First Supplemental
Indenture, 

  
 - 5 - 







 
the Notes do not constitute, or within 90 days of the date of such opinion will not constitute, Tier 2 Capital (or its then equivalent if the Company were subject to such capital requirement) for
purposes of capital adequacy guidelines of the FRB (or its then equivalent if the Company were subject to such capital requirement) for purposes of capital adequacy guidelines of the FRB (or any successor regulatory authority with jurisdiction over
bank holding companies), as then in effect and applicable to the Company. 
 The terms “Company,”
“Trustee,” “Base Indenture,” and “Notes” shall have the respective meanings set forth in the recitals to this First Supplemental Indenture and the paragraph preceding such recitals. 

ARTICLE 2 
 GENERAL TERMS
AND CONDITIONS OF THE NOTES 
 Section 2.01 Designation and Principal Amount. There is hereby established and authorized a
series of Securities designated as the “5.75% Fixed-to-Floating Rate Subordinated Notes due 2025” (the “Notes”) having an initial aggregate principal amount of $250,000,000 (except for Notes authenticated and delivered
upon registration of transfer of, or in exchange for, or in lieu of, other Notes pursuant to Sections 2.07, 2.08 or 2.10 of the Base Indenture and except for Notes which, pursuant to Section 2.02 of the Base Indenture, are deemed to never have
been authenticated and delivered under the Base Indenture). The Notes may be issued from time to time upon written order of the Company for the authentication and delivery of Notes pursuant to Sections 2.01 and 2.02 of the Base Indenture. 

Section 2.02 Maturity. The date upon which the Notes shall become due and payable at final maturity, together with any accrued and
unpaid interest, is December 15, 2025 (the “Maturity Date”). 
 Section 2.03 Form, Payment and
Appointment. Except as provided in Sections 2.07, 2.08 and 2.10 of the Base Indenture, the Notes will be issued only in book-entry form. Principal of and interest on the Notes will be payable in global form without interest coupons
registered in the name of or held by The Depository Trust Company (“DTC”) or its nominee in immediately available funds to DTC or its nominee, as the case may be, as the Holder of such Global Note (as hereafter defined). The
principal of any certificated Notes will be payable at the office or agency of the Company maintained for such purpose in New York, New York, which shall initially be the principal office of the Trustee in New York, New York; provided,
however, that payment of interest may be made at the option of the Company by check mailed to the Person entitled thereto at such address as shall appear in the Security Register or by wire transfer to an account appropriately designated by the
Person entitled to payment; provided that the Paying Agent shall have received written notice of such account designation at least five Business Days prior to the date of such payment (subject to surrender of the relevant Note in the case of
a payment of interest on the Maturity Date). 
 The Security Registrar, Authenticating Agent and Paying Agent for the Notes shall initially
be the Trustee. 

  
 - 6 - 







 The Notes will be issuable and may be transferred only in denominations of $2,000 or any amount
in excess thereof that is an integral multiple of $1,000. The specified currency of the Notes shall be U.S. Dollars. 
 The Notes shall not
be issued in bearer form and shall be issued only against payment in immediately available funds. 
 Section 2.04 Global Note.
The Notes shall be issued initially in the form of one or more fully registered global notes (each such global note, a “Global Note”) deposited with DTC or its designated custodian or such other Depositary as any officer of the
Company may from time to time designate. Unless and until a Global Note is exchanged for Notes in certificated form, such Global Note may be transferred, in whole but not in part, and any payments on the Notes shall be made, only to DTC or a nominee
of DTC, or to a successor Depositary selected or approved by the Company or to a nominee of such successor Depositary. 

Section 2.05 Interest. (a) Interest payable on any Interest Payment Date or the Maturity Date with respect to the Notes shall
be the amount of interest accrued from, and including, the immediately preceding Interest Payment Date in respect of which interest has been paid or duly provided for (or from and including the original issue date of December 7, 2015, if
no interest has been paid or duly provided for with respect to the Notes) to, but excluding, such Interest Payment Date or Maturity Date as the case may be. 

(b) The Notes will bear interest at a fixed rate of 5.75% per annum from and including December 7, 2015 to, but excluding,
December 15, 2020 (or earlier redemption) (the “Fixed Rate Period”). Interest accrued on the Notes during the Fixed Rate Period will be payable semi-annually in arrears on June 15 and December 15 of each year,
commencing on June 15, 2016 (each such date a “Fixed Rate Interest Payment Date”). The interest accrued during the Fixed Rate Period will be paid to each holder in whose name a Note is registered at the close of business
on June 1 and December 1 (whether or not a Business Day) immediately preceding the applicable Fixed Rate Interest Payment Date. 

(c) The Notes will bear a floating interest rate from and including December 15, 2020 to, but excluding, the Maturity Date (or
earlier redemption) (the “Floating Rate Period”). The floating interest rate will be equal to LIBOR for each applicable Interest Period plus 418.2 basis points. Interest accrued on the Notes during the Floating Rate Period
will be payable quarterly in arrears on March 15, June 15, September 15, and December 15 of each year (each such date, a “Floating Rate Interest Payment Date,” and together with a Fixed Rate Interest Payment
Date, an “Interest Payment Date”). The interest accrued during the Floating Rate Period will be paid to each holder in whose name a Note is registered at the close of business on the March 1, June 1, September 1, and
December 1 (whether or not a Business Day) immediately preceding the applicable Floating Rate Interest Payment Date. 
 (d) Interest
will be computed on the basis of a 360-day year consisting of twelve 30-day months during the Fixed Rate Period, and, thereafter, a 360-day year and the number of days actually elapsed. 

  
 - 7 - 







 (e) In the event that any scheduled Interest Payment Date for the Notes falls on a day that is
not a Business Day, then payment of interest payable on such Interest Payment Date will be postponed to, and shall be due on, the next succeeding day which is a Business Day with the same force and effect as if such payment was made on the
originally scheduled Interest Payment Date (and no interest on such payment will accrue for the period from and after such scheduled Interest Payment Date). 

(f) In the event that the Maturity Date for any Note falls on a day that is not a Business Day with the same force and effect as if such
payment was made on the originally scheduled Maturity Date, then the related payments of principal, premium, if any, and interest may be made, and shall be due on, on the next succeeding day that is a Business Day (and no additional interest will
accrue on the amount payable for the period from and after the Maturity Date). Interest due on the Maturity Date (whether or not an Interest Payment Date) of any Notes will be paid to the Person to whom principal of such Notes is payable. 

(g) Any interest which is payable, but is not punctually paid or duly provided for, on any Interest Payment Date (“Defaulted
Interest”) shall cease to be payable to the holder on the relevant record date by virtue of having been a holder on such date, and such Defaulted Interest may be paid by the Company, either to the holder in whose name the Notes are
registered at the close of business on a special record date for the payment of defaulted interest, or in any other lawful manner deemed practicable by the Trustee. 

Section 2.06 No Sinking Fund. The Notes are not entitled to the benefit of any sinking fund and any provision of the Base
Indenture relating to a sinking fund shall not be applicable to the Notes. 
 Section 2.07 Defeasance. Section 8.05 and
8.06 of the Base Indenture shall be applicable to the Notes. However, and in addition, any defeasance of the Notes pursuant to the Base Indenture shall be subject to the Company obtaining the prior approval of the FRB and any additional requirements
that the FRB may impose with respect to defeasance of the Notes. Notwithstanding the foregoing, if, due to a change in law, regulation or policy subsequent to the date of this First Supplemental Indenture, the FRB does not require that defeasance of
instruments be subject to FRB approval in order for the instrument to be accorded Tier 2 Capital treatment, then no such approval of the FRB will be required for such defeasance. 

Section 2.08 Satisfied and Discharged. Section 8.01 of the Base Indenture shall be applicable to the Notes. 

Section 2.09 Additional Issuances. The Company may from time to time, without notice to, or the consent of, the holders of the
Notes, create and issue further notes ranking equally with the Notes and with identical terms in all respects (or in all respects except for the offering price, the payment of interest accruing prior to the issue date of such further notes or the
first payment of interest following the issue date of such further notes) in order that such further notes may be consolidated and form a single series of Notes and have the same terms as to status, redemption or otherwise as the notes; provided,
however, that a separate CUSIP number shall be issued for any such additional notes unless the notes are fungible for U.S. federal income tax purposes, subject to the procedures of DTC.

 ARTICLE 3 

REDEMPTION 
 The following
redemption provisions shall apply to the Notes. 
 Section 3.01 Applicability of Article. (a) The Company may, at its
option, beginning with the Interest Payment Date of December 15, 2020, but not prior thereto (except as provided in paragraph (b) below), and on any Interest Payment Date thereafter, redeem the Notes, in whole or in part, subject to
obtaining the prior approval of the FRB to the extent such approval is then required under the rules of the FRB, at a redemption price equal to 100% of the principal amount of the Notes to be redeemed plus accrued and unpaid interest to, but
excluding, the date of redemption. 
 (b) The Notes may not otherwise be redeemed prior to the Maturity Date, except that the Company may
also, at its option, redeem the Notes before the Maturity Date in whole or in part upon the occurrence of (i) a Tax Event, (ii) a Tier 2 Capital Event, or (iii) the Company becoming required to register as an investment company
pursuant to the Investment Company Act of 1940, as amended, in each case, at a redemption price equal to 100% of the principal amount of the Notes to be redeemed plus accrued and unpaid interest to, but excluding, the date of redemption. Any
redemption pursuant to this paragraph (b) is subject to the prior approval of the FRB to the extent such approval is then required under the rules of the FRB. 

(c) The Notes will not be redeemable at the option of the Company except as set forth in this Article 3. Notice of redemption shall be given
in accordance with Article 3 of the Base Indenture. Notice of redemption of the Notes to be redeemed at the election of the Company shall be given by the Company or, at the Company’s request, by the Trustee in the name and at the expense
of the Company. Notwithstanding the foregoing, or any provisions contained in the Base Indenture to the contrary, any notice of redemption (and the making of any redemption payment) may be conditional at the Company’s discretion on one or more
condition(s) precedent, and, the redemption date (and the making of any redemption payment) may be delayed until such time as any or all of such conditions have been satisfied or revoked by the Company if the Company determines that such
condition(s) will not be satisfied. 
 (d) The Notes are not subject to redemption or prepayment at the option of the Holders of the Notes.

 (e) Any partial redemption of the Notes pursuant to this Article 3 will be made pro rata among all of the Holders of the Notes.

apply to any redemption hereunder.

 ARTICLE 4 

SUBORDINATION 
 The
following subordination provisions shall apply to the Notes. 
 Section 4.01 Notes Subordinate to Senior Debt. The Company
covenants and agrees that anything herein or the Notes to the contrary notwithstanding, the indebtedness evidenced by the Notes is subordinate and junior in right of payment to all Senior Debt to the extent provided herein, and each Holder of Notes,
by such Holder’s acceptance of such Notes, likewise covenants and agrees to the subordination provided for in this Article 4 and shall be bound by the provisions herein. Senior Debt shall continue to be Senior Debt and entitled to the benefits
of these subordination provisions irrespective of any amendment, modification, or waiver of any term of the Senior Debt or extension or renewal of the Senior Debt. 

In the event of: 
 (a) any
insolvency, bankruptcy, receivership, liquidation, reorganization, readjustment of debt, composition, or other similar proceeding relating to the Company or its property, 

(b) any proceeding for the liquidation, dissolution, or other winding up of the Company, whether voluntary or involuntary and whether or not
involving insolvency or bankruptcy proceedings, 
 (c) any assignment by the Company for the benefit of creditors, or 

(d) any other marshalling of the assets of the Company, 

all obligations with respect to all Senior Debt shall first be paid in full before any payment or distribution, whether in cash, securities, or other
property, shall be made to any Holder of the Notes on account of the principal or interest on the Notes. Only after payment in full of all amounts owing with respect to Senior Debt shall the Holders of the Notes, together with holders of any
obligations of the Company Ranking on a Parity with the Notes, be entitled to be paid from any remaining assets of the Company on account of the principal of, or unpaid interest on, the Notes. Any payment or distribution, whether in cash,
securities, or other property (other than securities of the Company or any other Person provided for by a plan of reorganization or readjustment the payment of which is subordinate, at least to the extent provided in these subordination provisions
with respect to the indebtedness evidenced by the Notes, to the payment of all Senior Debt at the time outstanding and to any securities issued in respect of such Senior Debt under any such plan of reorganization or readjustment), which would
otherwise (but for these subordination provisions) be payable or deliverable in respect of the Notes shall be paid or delivered directly to the holders of Senior Debt in accordance with the priorities then existing among such holders until all
Senior Debt (including any interest on such Senior Debt accruing after the commencement of any such proceedings) shall have been paid in full. In the event of any such proceeding, after payment in full of all sums owing with respect to Senior Debt,
the Holders of the Notes, together with the holders of any obligations of the Company ranking on a parity with the Notes, shall be entitled to be paid from the remaining assets of the Company the amounts at the


  
 - 10 - 







 
time due and owing on account of unpaid principal of (and premium, if any) and interest on the Notes and such other obligations before any payment or other distribution, whether in cash,
property, or otherwise, shall be made on account of any capital stock or any obligations of the Company ranking junior to the Notes and such other obligations. 

In the event that, notwithstanding the foregoing, any payment or distribution of any character or any security, whether in cash, securities,
or other property (other than securities of the Company or any other corporation provided for by a plan of reorganization or readjustment the payment of which is subordinate, at least to the extent provided in these subordination provisions with
respect to the indebtedness evidenced by the Notes, to the payment of all Senior Debt at the time outstanding and to any securities issued in respect of such Senior Debt under any such plan of reorganization or readjustment), shall be received by
the Trustee or any Holder in contravention of any of the terms herein, such payment or distribution or security shall be received in trust for the benefit of, and shall be paid over or delivered and transferred to, the holders of the Senior Debt at
the time outstanding in accordance with the priorities then existing among such holders for applications to the payment of all Senior Debt remaining unpaid, to the extent necessary to pay all such Senior Debt in full. In the event of the failure of
the Trustee or any Holder of the Notes to endorse or assign any such payment, distribution, or security, each holder of Senior Debt is irrevocably authorized to endorse or assign the same. 

No present or future holder of any Senior Debt shall be prejudiced in the right to enforce subordination of the indebtedness evidenced by the
Notes by any act or failure to act on the part of the Company. Nothing contained herein shall impair, as between the Company and the Holders of the Notes, the obligation of the Company to pay to such Holders the principal of, (and premium, if any),
and interest on, such Notes or prevent the Trustee or the Holder from exercising all rights, powers and remedies otherwise permitted by applicable law or under the Base Indenture or this First Supplemental Indenture upon a default or Event of
Default, all subject to the rights of the holders of the Senior Debt to receive cash, securities, or other property otherwise payable or deliverable to the Holders. 

Senior Debt shall not be deemed to have been paid in full unless the holders shall have received cash, securities, or other property equal to
the amount of such Senior Debt then outstanding. Upon the payment in full of all Senior Debt, the Holders of the Notes shall be subrogated to all rights of any holders of Senior Debt to receive any further payments or distributions applicable to the
Senior Debt until the indebtedness evidenced by the Notes shall have been paid in full, and such payments or distributions received by such Holders, by reason of such subrogation, of cash, securities, or other property which otherwise would be paid
or distributed to the holders of Senior Debt shall, as between the Company and its creditors other than the holders of Senior Debt, on the one hand, and such Holders, on the other hand, be deemed to be a payment by the Company on account of Senior
Debt, and not on account of the Notes. 
 The Trustee and Holders will take such action (including, without limitation, the delivery of this
First Supplemental Indenture to an agent for the holders of Senior Debt or consent to the filing of a financing statement with respect to this First Supplemental Indenture) as may, in the opinion of counsel designated by the holders of a majority in
principal amount of the Senior Debt at the time outstanding, be necessary or appropriate to assure the effectiveness of the subordination effected by these provisions. 

  
 - 11 - 







 The provisions of this Section 4.01 shall not impair any rights, interests, remedies, or
powers of any secured creditor of the Company in respect of any security interest the creation of which is not prohibited by the provisions herein. 

Section 4.02 No Payment When Senior Debt in Default. (a) In the event and during the continuation of any default in the
payment of the principal of, or any premium or interest on, any Senior Debt beyond any applicable grace period with respect to such Senior Debt, or in the event that any event of default with respect to any Senior Debt shall have occurred and be
continuing permitting the holders of such Senior Debt (or the trustee or agent on behalf of the holders of such Senior Debt) to declare such Senior Debt due and payable prior to the date on which it would otherwise have become due and payable,
unless and until such event of default shall have been cured or waived or shall have ceased to exist and such acceleration shall have been rescinded or annulled, or (b) in the event any judicial proceeding shall be pending with respect to any
such default in payment or event of default, then no payment (including any payment which may be payable by reason of the payment of any other indebtedness of the Company being subordinated to the payment of the Notes) shall be made by the Company
on account of the principal of, or any premium or interest on, the Notes or on account of the purchase or other acquisition of Notes. 
 In
the event that, notwithstanding the foregoing, the Company shall make any payment to the Trustee or the Holders prohibited by the foregoing provisions of this Section 4.02 and if such fact shall, at or prior to the time of such payment, have
been made known to a Responsible Officer of the Trustee or, as the case may be, such Holder, then and in such event such payment shall be paid over and delivered to the Company or to the holders of Senior Debt. 

Section 4.03 Trustee and Holders of Notes May Rely on Certificate of Liquidating Agent; Trustee May Require Further Evidence as to
Ownership of Senior Debt; Trustee Not Fiduciary to Holders of Senior Debt. Upon any payment or distribution of assets of the Company referred to in this Article 4, the Trustee and the Holders shall be entitled to rely upon an order or decree
made by any court of competent jurisdiction in which such dissolution or winding up or liquidation or reorganization or arrangement proceedings are pending or upon a certificate of the trustee in bankruptcy, receiver, assignee for the benefit of
creditors, or other Person making such payment or distribution, delivered to the Trustee or to the Holders, for the purpose of ascertaining the persons entitled to participate in such distribution, the holders of the Senior Debt and other
indebtedness of the Company, the amount of or payable on and the amount or amounts paid or distributed on such Senior Debt or other indebtedness, and all other facts pertinent to such Senior Debt or other indebtedness or to this Article 4. In the
absence of any such bankruptcy trustee, receiver, assignee, or other Person, the Trustee shall be entitled to rely upon a written notice by a Person representing himself or herself to be a holder of Senior Debt (or a trustee or representative on
behalf of such holder) as evidence that such Person is a holder of such Senior Debt (or is such a trustee or representative). In the event that the Trustee determines, in good faith, that further evidence is required with respect to the right of any
Person as a holder of Senior Debt to participate in any payments or distributions pursuant to this Article 4, the Trustee may request such person to furnish evidence to the reasonable satisfaction of the Trustee as to the amount of Senior Debt held
by such Person, as to the extent to which such Person is entitled to participate in such payment or 

  
 - 12 - 







 
distribution, and as to other facts pertinent to the rights of such Person under this Article 4, and if such evidence is not furnished, the Trustee may offer any payment to such Person pending
judicial determination as to the right of such Person to receive payment. The Trustee, however, shall not be deemed to owe any fiduciary duty to the holders of Senior Debt. 

Section 4.04 Payment Permitted If No Default. Nothing contained in this Article 4 or elsewhere herein, or the Notes, shall prevent
(a) the Company at any time, except during the pendency of a Proceeding or under the conditions specified in Section 4.02, from making payments of the principal of, or interest on, the Notes or (b) the application by the Trustee or
any Paying Agent of any moneys deposited with it hereunder to payments of the principal of or interest on the Notes, if, at the time of such deposit, the Trustee or such Paying Agent, as the case may be, did not have the written notice provided for
in Section 4.05 of any event prohibiting the making of such deposit, or if, at the time of such deposit (whether or not in trust) by the Company with the Trustee or any Paying Agent (other than the Company) such payment would not have been
prohibited by the provisions of this Article, and the Trustee or any Paying Agent shall not be affected by any notice to the contrary received by it on or after such date. 

Section 4.05 Trustee Not Charged with Knowledge of Prohibition. Anything in this Article 4 or elsewhere contained herein to the
contrary notwithstanding, the Trustee shall not at any time be charged with knowledge of the existence of any facts which would prohibit the making of any payment of money to or by the Trustee and shall be entitled conclusively to assume that no
such facts exist and that no event specified in Section 4.01 or Section 4.02 has happened, until the Trustee shall have received an Officers’ Certificate at least three Business Days prior to the date on which any payment should be
made, to that effect or notice in writing to that effect signed by or on behalf of the holder or holders, or their representatives, of Senior Debt who shall have been certified by the Company or otherwise established to the reasonable satisfaction
of the Trustee to be such holder or holders or representatives or from any trustee under any indenture pursuant to which such Senior Debt shall be outstanding. The Company shall give prompt written notice to the Trustee and to the Paying Agent of
any facts which would prohibit the payment of money to or by the Trustee or any Paying Agent. 
 Section 4.06 Trustee to Effectuate
Subordination. Each Holder of the Notes by such Holder’s acceptance authorizes and directs the Trustee in such Holder’s behalf to take such action as may be necessary or appropriate to effectuate the subordination as between such
Holder and holders of Senior Debt as provided in this Article and appoints the Trustee its attorney-in-fact for any and all such purposes. 

Section 4.07 Rights of Trustee as Holder of Senior Debt. The Trustee shall be entitled to all the rights set forth in this Article
with respect to any Senior Debt which may at the time be held by it, to the same extent as any other holder of Senior Debt; provided that nothing in this Article shall deprive the Trustee of any rights as such holder and provided further that
nothing in this Article shall apply to claims of, or payments to, the Trustee under or pursuant to Section 7.07 of the Base Indenture. 

Section 4.08 Article Applicable to Paying Agents. In case at any time any Paying Agent other than the Trustee shall have been
appointed by the Company and be then acting under the 

  
 - 13 - 







 
Base Indenture with respect to the Notes, the term “Trustee” as used in this Article shall in such case (unless the context shall otherwise require) be construed as extending to and
including such Paying Agent within its meaning as fully for all intents and purposes as if the Paying Agent were named in this Article in addition to or in place of the Trustee, provided, however, that Sections 4.05 and 4.07 shall not apply to
the Company or any Affiliate of the Company if the Company or such Affiliate acts as Paying Agent. 
 Section 4.09 Subordination
Rights Not Impaired by Acts or Omissions of the Company or Holders of Senior Debt. No right of any present or future holders of any Senior Debt to enforce subordination as provided herein shall at any time in any way be prejudiced or impaired by
any act or failure to act on the part of the Company or by any act or failure to act, in good faith, by any such holder, or by any noncompliance by the Company with the terms, provisions, and covenants hereto, regardless of any knowledge which any
such holder may have or be otherwise charged with. The holders of Senior Debt may, at any time or from time to time and in their absolute discretion, change the manner, place, or terms of payment, change or extend the time of payment of, or renew or
alter, any such Senior Debt, or amend or supplement any instrument pursuant to which any such Senior Debt is issued or by which it may be secured, or release any security, or exercise or refrain from exercising any other of their rights under the
Senior Debt, including, without limitation, the waiver of default, all without notice to or assent from the Holders of the Notes or the Trustee and without affecting the obligations of the Company, the Trustee, or the Holders of the Notes under this
Article. 
 Section 4.10 Modification of Subordination Provisions. Anything contained herein or in the Base Indenture to the
contrary notwithstanding, no modification or amendment and no supplemental indenture shall modify the subordination provisions of this Article 4 in a manner that would adversely affect the holders of Senior Debt. 

Section 4.11 Application of Money Collected. With respect to the Notes, notwithstanding Section 6.03 of the Base Indenture,
any monies collected by the Trustee pursuant to Article 6 of the Base Indenture in any Proceeding shall be applied in the following order (but otherwise in accordance with Section 6.03 of the Base Indenture): 

FIRST: To the payment of all amounts due the Trustee under Section 7.07 of the Base Indenture; 

SECOND: To the payment of amounts then due and unpaid to the holders of Senior Debt, to the extent required by this Article 4; and 

THIRD: To the payment of the amounts then due and unpaid for principal of and any premium and interest on the Notes in respect of which or for
the benefit of which such money has been collected, ratably, without preference or priority of any kind, according to the amounts due and payable on such Notes for principal and any premium and interest, respectively. 

Section 4.12 Subordination Provisions of Base Indenture. To the extent not inconsistent with the foregoing Sections 4.01
through 4.11, the provisions of Article 11 of the Base Indenture shall apply to the Notes as if “Senior Indebtedness” thereunder were “Senior Debt” hereunder.

	No. R-1	 		 	$250,000,000

 Synovus Financial Corp., a corporation duly organized and existing under the laws of the State of Georgia (hereinafter called
the “Company”, which term includes any successor corporation under the Indenture hereinafter referred to), for value received, hereby promises to pay to CEDE & Co., or registered assigns the principal sum of TWO HUNDRED
FIFTY MILLION UNITED STATES DOLLARS on December 15, 2025 (such date is hereinafter referred to as the “Maturity Date”), and to pay interest thereon, as hereinafter set forth. 

This Note will bear interest at a fixed rate of 5.75% per annum from and including December 7, 2015 to but excluding
December 15, 2020 (the “Fixed Rate Period”). Interest accrued on this Note during the Fixed Rate Period will be payable semi-annually in arrears on June 15 and December 15 of each year, commencing on
June 15, 2016 (each such date a “Fixed Rate Interest Payment Date”). The interest accrued during the Fixed Rate Period will be paid to each holder in whose name a Note is registered at the close of business on June 1
and December 1 (whether or not a Business Day) immediately preceding the applicable Fixed Rate Interest Payment Date. 
 This Note will bear a floating
interest rate from and including December 15, 2020 to but excluding the Maturity Date or earlier redemption (the “Floating Rate Period”). The floating interest rate will be equal to LIBOR for each applicable Interest
Period plus 418.2 basis points. Interest accrued on this Note during the Floating Rate Period will be payable quarterly in arrears on March 15, June 15, September 15 and December 15 of each year (each such date, a
“Floating Rate Interest Payment Date”, together with a “Fixed Rate Interest Payment Date”, an “Interest Payment Date”). The interest accrued during the Floating Rate Period will be paid to each
holder in whose name a Note is registered at the close of business on the March 1, June 1, September 1 and December 1 (whether or not a Business Day) immediately preceding the applicable Floating Rate Interest Payment Date. 

“Interest Period” shall mean, initially, the period from December 15, 2020 and ending on the day preceding the first Floating Rate
Interest Payment Date occurring after such date and, thereafter, the period commencing on each Floating Rate Interest Payment Date and ending on the day preceding the next Floating Rate Payment Date. 

“LIBOR” means the rate as published by Bloomberg (or another commercially available source providing quotations of such rate as selected by
the Company from time to time) at approximately 

  
 A-2 







 
11:00 a.m., London time, two Business Days prior to the commencement of the relevant applicable quarterly Interest Period, as the rate for dollar deposits in the London interbank market with a
three-month maturity. If such rate is not available at such time for any reason, then the rate for that Interest Period will be determined by such alternate method as reasonably selected by the Company. 

Interest will be computed on the basis of a 360-day year consisting of twelve 30-day months from and including December 7, 2015 to, but excluding,
December 15, 2020, and, thereafter, a 360-day year and the number of days actually elapsed. 
 In the event that any scheduled Interest Payment
Date for the Notes falls on a day that is not a Business Day, then payment of interest payable on such Interest Payment Date will be postponed to, and shall be due on, the next succeeding day which is a Business Day with the same force and effect as
if such payment was made on the originally scheduled Maturity Date (and no interest on such payment will accrue for the period from and after such scheduled Interest Payment Date). 

In the event that the Maturity Date for the Notes falls on a day that is not a Business Day, then the related payments of principal, premium, if any, and
interest may be made, and shall be due on, the next succeeding day that is a Business Day with the same force and effect as if such payment was made on the originally scheduled Interest Payment Date (and no additional interest will accumulate on the
amount payable for the period from and after the Maturity Date). Interest due on the Maturity Date (whether or not an Interest Payment Date) of any Notes will be paid to the Person to whom principal of such Notes is payable. 

Payment of the principal of and interest on this Note will be made at the office or agency of the Company maintained for that purpose in New York, New York,
which shall initially be the principal office of the Trustee located therein, in such coin or currency of the United States of America as at the time of payment is legal tender for payment of public and private debts; provided, however, that
payment of interest may be made at the option of the Company by check mailed to the Person entitled thereto at such address as shall appear in the Security Register (subject to surrender of the relevant Note in the case of a payment of interest on
the Maturity Date). 
 Reference is hereby made to the further provisions of this Note set forth on the reverse hereof, which further provisions shall for
all purposes have the same effect as if set forth at this place. 
 Unless the certificate of authentication hereon has been executed by the Trustee
referred to on the reverse hereof by manual or facsimile signature, this Note shall not be entitled to any benefit under the Indenture or be valid or obligatory for any purpose.

 REVERSE OF NOTE 

SYNOVUS FINANCIAL CORP. 
 This Note is one of a
duly authorized issue of securities of the Company (herein called the “Note”), issued and to be issued in one or more series under an Indenture (the “Base Indenture”), dated as of December 7, 2015, between
the Company and The Bank of New York Mellon Trust Company, N.A., as Trustee (herein called the “Trustee,” which term includes any successor trustee), as amended and supplemented by the First Supplemental Indenture between the
Company and the Trustee (the “First Supplemental Indenture” and together with the Base Indenture, the “Indenture”) dated as of December 7, 2015, to which Indenture reference is hereby made for a statement
of the respective rights, limitations of rights, duties and immunities thereunder of the Company, the Trustee and the Holders of the Notes and of the terms upon which the Notes are, and are to be, authenticated and delivered. This Note is one of the
series designated on the face hereof, initially limited in aggregate principal amount to $250,000,000. The terms of this Note include those stated in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act. This
Note is subject to all such terms, and Holders are referred to the Indenture and the Trust Indenture Act for a statement of such terms. To the extent any provision of this Note conflicts with the express provisions of the Indenture, the provisions
of the Indenture shall govern and be controlling (to the extent permitted by law). 
 All terms used in this Note that are defined in the Indenture shall
have the meaning assigned to them in the Indenture. 
 The Company may, at its option, beginning with the Interest Payment Date of
December 15, 2020, but not prior thereto (except as provided below), and on any Interest Payment Date thereafter, redeem the Notes, in whole or in part, subject to obtaining the prior approval of the FRB to the extent such approval is then
required under the rules of the FRB, at a redemption price equal to 100% of the principal amount of the Notes to be redeemed plus accrued and unpaid interest to, but excluding, the date of redemption. 

The Notes may not otherwise be redeemed prior to the Maturity Date, except that the Company may also, at its option (but subject to the prior approval of the
FRB to the extent such approval is then required under the rules of the FRB), redeem the Notes before the Maturity Date in whole, at any time, or in part from time to time, upon the occurrence of (i) a Tax Event, (ii) a Tier 2 Capital
Event, or (iii) the Company becoming required to register as an investment company pursuant to the Investment Company Act of 1940, as amended, in each case, at a redemption price equal to 100% of the principal amount of the Notes to be redeemed
plus accrued and unpaid interest to, but excluding, the date of redemption. 
 The Notes will not be redeemable at the option of the Company except as set
forth in Article 3 of the First Supplemental Indenture. Notice of redemption shall be given in accordance with Article 3 of the Base Indenture. Any partial redemption of the Notes will be made pro rata among all of the Holders of the Notes.
Notice of redemption of the Notes to be redeemed at the election of the Company shall be given by the Company or, at the Company’s request, by the Trustee in the name and at the expense of the Company. 

  
 A-6 







 Any notice of redemption may be conditional at the Company’s discretion on one or more conditions precedent,
and the redemption date may be delayed until such time as any or all of such conditions have been satisfied or revoked by the Company if the Company determines that such condition(s) will not be satisfied. 

The Notes are not subject to redemption or prepayment at the option of the Holders of the Notes. The Notes are not entitled to the benefit of any sinking
fund. 
 If one or more of the Events of Default identified in Article 5 of the First Supplemental Indenture with respect to Notes shall occur and be
continuing, the principal of the Notes shall become immediately due and payable in the manner and with the effect provided in the Indenture. Except solely upon the occurrence of such Events of Default specified in Article 5 of the First
Supplemental Indenture, the Trustee and/or the Holders of Notes shall have no right to declare the Notes, and any accrued but unpaid interest, and premium, if any, on the Notes, to be immediately due and payable. 

The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Company
and the rights of the Holders of the Notes at any time by the Company and the Trustee with the consent of the Holders of a majority in principal amount of the Notes affected thereby and at the time Outstanding. The Indenture also contains provisions
permitting the Holders of a majority in principal amount of the Notes at the time Outstanding, on behalf of the Holders of all Notes, to waive certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder
of this Note shall be conclusive and binding upon such Holder and upon all future Holders of this Note and of any Note issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent
or waiver is made upon this Note. 
 As provided in the Indenture and subject to certain limitations therein set forth, the transfer of this Note is
registrable in the Security Register, upon surrender of this Note for registration of transfer at the office or agency of the Company in any place where the principal of and interest on this Note are payable, duly endorsed by, or accompanied by a
written instrument of transfer in form satisfactory to the Company and the Security Registrar duly executed by the Holder hereof or his attorney duly authorized in writing, and thereupon one or more new Notes, of authorized denominations and for the
